Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 29

Sanskrit:

जन्म ते मय्यसौ पापो मा विद्यान्मधुसूदन ।समुद्विजे भवद्धेतो: कंसादहमधीरधी: ॥ २९ ॥

ITRANS:

janma te mayy asau pāpomā vidyān madhusūdanasamudvije bhavad-dhetoḥkaṁsād aham adhīra-dhīḥ

Translation:

O Madhusūdana, because of Your appearance, I am becoming more and more anxious in fear of Kaṁsa. Therefore, please arrange for that sinful Kaṁsa to be unable to understand that You have taken birth from my womb.

Purport:

Devakī addressed the Supreme Personality of Godhead as Madhusūdana. She was aware that the Lord had killed many demons like Madhu who were hundreds and thousands of times more powerful than Kaṁsa, yet because of affection for the transcendental child, she believed that Kaṁsa could kill Him. Instead of thinking of the unlimited power of the Lord, she thought of the Lord with affection, and therefore she requested the transcendental child to disappear.
